Following is a portrayal of the upcoming conjunction
of Jupiter and Venus:

Here is an aricle that describes the possibility that
it was a conjunction of planets that heralded Christ's
first coming, and possibly could have been known as
the "Star of Bethlehem".  Below are quotes from the
link concerning the planetary conjunctions:

"The triple conjunction of Jupiter and Saturn in 7
B.C. was seen in the constellation Pisces in the
months of May, September, and December. This provides
sufficient time for the magi to see the first
conjunction, begin their trip west to Judea, visit
Herod by the second conjunction or at least soon
afterwards, and perhaps not reach Bethlehem until the
third conjunction when it is said to have appeared in
the southern sky, and Bethlehem is just south of
Jerusalem. Remember how the magi rejoiced to see the
star again as they departed Jerusalem for Bethlehem.
Ancient astrologers associated Jupiter with royalty or
even a ruler of the universe. Saturn was associated
with Palestine or even with the deity who protected
Israel. And Pisces was associated with the nation of
Israel. Later a massing of Jupiter, Mars, and Saturn
occurred again in Pisces in 6 B.C. It seems feasible
then that this triple conjunction followed by the
massing of the three planets in Pisces could indicate
to the magi that a King of Israel and a Ruler of the
Universe was about to be born in Israel. . .

Remember that Jupiter is considered the royal star.
Well, in 3 B.C., Jupiter came into conjunction with
Regulus, the star of kingship, the brightest star in
the constellation of Leo, the first of several such
conjunctions over the next year. Leo was the
constellation of kings, and it was also closely
associated by some with the Lion of Judah. This is
beginning to look interesting. "The royal planet
approached the royal star in the royal constellation
representing Israel."(1) In addition, on September 11,
3 B.C., Jupiter was not only very close to Regulus,
but the sun was in the constellation Virgo. Hmmm, the
royal planet in conjunction with the royal star while
the sun is in a virgin. September 11, 3 B.C., is also
the beginning of the Jewish New Year. There seems to
be an awful lot coming together here."

(This is also reminiscent of Venus aligning within 1/4
of a degree with Regulus which happened about a week
ago.  Venus is the bright and morning star which
represents Jesus.)
